October 12, at 9: Liquid scintillation counting is another radiocarbon dating technique that was popular in the s. The cross section analogous to reaction probability in nuclear chemistry for the capture of thermalized neutrons by carbon is well-known. Tracer-Free AMS Dating Lab Beta Analytic does not accept pharmaceutical samples with "tracer Carbon" or any other material containing artificial Carbon to eliminate the risk of cross-contamination. The data you get are only as good as your specimen. Once an organism dies the carbon is no longer replaced.

How Does Carbon Dating Work
If even a small number of dinosaur bones are less thanold, it throws a monkey wrench into the whole evolutionary timeline.

I encourage people to check lots of resources, as no single resource is completely reliable. Pre-Columbian chickens, dates, isotopes, and mtDNA. If the expert says all samples, even those that contain no C, appear to show some level of C, then that is the way it probably is.
